mv^2 =2* e*40k J/Cv= sqrt(2* e*40k/m)
mv^2/r = F centripetal = evB2* e*40k/(210*sqrt(2* e*40k/m)*e) =BB=√e∗80,000∗m−−−−−−−−−−−/210
Answer: prokaryotic cells have no nucleus, no organelles and a small amount of DNA. Eukaryotic cells do have a nucleus, along with many organelles, and more DNA.
Explanation:
Answer: Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
